Noise and Thermal Testing, Dedicated GPUs

It's funny, when we put together the revised testbeds, the Zotac GeForce GTS 450 Eco was chosen because it employed a single-slot cooler and would be indicative of the kind of video card most HTPCs would use. Yet many modern Mini-ITX cases (and even comparatively old standards like the SG05) include two expansion slots. The solution? Test the case with the GTS 450 and our standard ATX testbed card, the ASUS GeForce GTX 560 Ti! That's exactly what I've done here with the SilverStone Sugo SG05.

CPU Temperatures with GTS 450

CPU temperatures are still pretty solid and consistent with the SG05, even when we include the GTX 560 Ti with its 170-watt TDP. Note that idle thermals actually increase a little with the GTS 450; I suspect this is at least partly due to the way the 560 Ti directs airflow directly at the CPU by effectively blocking the front of the video card off completely from the rest of the system.

GTX 560 Ti Temperatures

The SG05 again produces moderate temperatures for both the GTX 560 Ti and the GTS 450. In fact, impressively enough the GTX 560 Ti's temperatures are roughly on par with many ATX cases; the ventilation on the side of the SG05 definitely seems to be doing its job.

SSD Temperatures with GTS 450

Unfortunately, SSD temperatures are where things get a bit sticky with the GTX 560 Ti. Because of the way it blocks off the side vent coupled with the heat it generates, airflow around the drive bay winds up being fairly minimal. Heat gets trapped between the video card and the drive bay, just like it does in Cooler Master's enclosure.

CPU Fan Speed with GTS 450

The CPU fan also seems to be working a bit harder, though ~2% is essentially within the margin of error. SilverStone's FT03 Mini has a superior airflow design for the CPU, no way around it. It shares the same basic chassis as the Sugo SG05, but enjoys a beefy 140mm Air Penetrator intake fan.

GTX 560 Ti Fan Speed

Once again fan speed falls in line, though I'm keen to point out the GTX 560 Ti's fan speed in the SG05 is actually comparable to some of our best ATX form factor case results. That extensive ventilation pays big dividends for SilverStone.

Noise Levels with GTS 450

The noise results bear out one of my main theories of case design, too: smart airflow design can do wonders for keeping noise levels low. By being a bit more closed off, Cooler Master's design actually increases the amount of noise generated since the fans have to work harder. The SG05 is by no means quiet, but it's not spectacularly loud either. I'm not sure you could really make a case this small that runs much quieter; at that point you really need to start cherry picking components.

    Silverstone have already released a SFF PSU that is 80 Plus Gold certified:

    By the gods that's one hot little number, and modular to boot! I looked it up on Newegg and they're selling it for $99USD right meow!

    The 450w power supply does get noisy. It's a very interesting case, my build is a few years old now and still going strong but it's been considerably modified over the years.

    I bought the original with the 300w PSU, had an i5 760 and a GTS250 back then. When I wanted to upgrade GPU the ST450-SF wasn't out so I went for a modular ATX PSU. A corsair H50 and a GTX570HD

    Still going strong, cool and quiet behind my TV (CPU idles at 27c and gets to 50 under load)

    Had to give up the 3.5" bay for the H50 and the optical & 2.5" bay for the PSU, then I fitted 500GB laptop HDD and a 60GB SSD to the botton on the case and problem solved.

    Silverstone has several other variants of the Sugo case with 600W PSUs. Using one of them should kill the PSU noise since anything smaller than a dual GPU card is unlikely to put enough load on it to ramp the fans above idle.

    Mine is not noisy :) it has an ATX PSU as you can see in the pictures

    "The great thing about reviewing these Mini-ITX cases is that oftentimes there just isn't a whole lot to them,"

    Lol! I love hearing little reviewer-centric quips like that.

    ...so I guess this means you have time to do even MORE reviews, eh?

    The coolermaster has some good points, but it needed endless mods. I pull the cheesy face plate off it and mounted an aluminum grill, It added air but the case needs custom cables to allow for proper airflow. So if you want a nice machine with the cooker master be prepared to break out a lot of tools. I am still playing with it.

    When I am done It will have an;

    i7 3770k

    a 256gb msata ssd

    a full size samsung blu ray

    a full size seasonic psu

    a geforce gtx 670

    all noctua fans .

    It will be nice when I am done but it is not worth the effort.

    My guess is this silverstone is better by far in terms of ease of assembly

    i built one a while ago

    Actually there's a *very* good reason to go with what you consider an unworthy 300W PSU: Better power efficiency at low power usage. Since it is almost impossible to cram equipment for 300W max consumption into such a case and even that is much more likely to run at <20% power utilisation rather than 80% it simply does not make any sense to have >300W PSU in a mini-ITX case.
